Product Details

The Cometic C5847-080 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Pontiac 400, 428, and 455 cubic inch V8 engines. This gasket features a 4.410-inch bore diameter and a compressed thickness of .080 inches, making it ideal for performance builds and engine rebuilds requiring precise compression control.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 4.410-inch bore diameter optimized for Pontiac V8 applications
  • .080-inch compressed thickness allows fine-tuning of compression ratios
  • Exceeds OEM gasket performance in high-heat and high-pressure conditions
  • Stainless steel construction resists corrosion and maintains seal integrity
  • Engineered for street performance, racing, and marine applications

Cometic MLS head gaskets utilize multiple layers of stainless steel with specialized coatings to create a superior seal between the cylinder head and engine block. The .080-inch thickness option provides flexibility for custom compression ratios in performance builds, while the precision-cut 4.410-inch bore ensures proper combustion chamber sealing for Pontiac 400, 428, and 455 engines.

Autoplicity was great, I ordered my springs late Monday night and I received a shipment order confirmation number early Wednesday. So basically 1 business day and my order was out the door, pretty impressive. Can't wait 'till it gets here! Thanks Autoplicity!

Easy to use website. Great prices. Fast shipping. Secure payment options. The only thing was their lack of follow up with the process. Checking the status of the order(9320) yielded no change, as far as when shipped and when eta would be. But regardless it came as expected and in great condition. Thx!!!!!

Best price I could find after hours of searching, I recommend 100%!!!

They had the best price on a hitch I was looking for and the shipping was fast also. The hitch was shipped bare except for taping the box of bolts to it thus leaving the hitch open and chipping the paint/powdercoating in quite a few places which I had to touch up before installing.

Easy to use website. The belts I ordered didn't have a picture but I knwew what I was looking for.
